/!\
WARNING:
Use
only crystal clear kerosene (Red dyed
or
clear kerosene
or low
sulphur
#1
oil). Neber
use
gasoline, white gas, camp fuel
or
other flammable liquids.
Use of
such Fuels
can
result
in an
explosive
fire
and
cause severe injury.
FUELING OPTIONS AVAILABLE
Fueling
of
your Monitor 2400 Heating System
can be
accomplished
in one of 2
ways:
1.
Gravity
Fed
Large Capacity External Tank:
Practical
for
large heating needs where bulk delivery
of
kerosene
is
available. This system should
be
installed
by a
qualified plumber
or
fuel supply
technician.
2.
Large
Capacity
External Tank
with
Pump:
For
large heating needs where
a
gravity
fed
system
is
not
practical.
An
electric lifter pump, especially
designed
for use
with
your
Monitor
2400
heating
system,
is
available
from
your dealer.
When
using
a
gravity
fed
tank
or
pumping system
to
supply
fuel,
the
inlet
pressure
to the
heater must
not
exceed
2.5
psi.
NOTE:lt
is
recmmended
to
install
the
fuel
line
on the
left
side
of the
unit,
with
an
appropriate
shut-off
valve,
and
then
across,
behind
the
unit,
to the
attachment
point
on the
right
rear
of the
heater.
EXTERNAL
TANK
INSTALLATION-
Gravity
Fed
NOTE:External
tank
installations
must
comply
with
the
National
Fire
Prtection
Association
code
NFPA
31
or
locally applicable codes, such
as the
Uniform
Mechanical
Code,
that
are
cnsistent
with
NFPA
31.
Check
with
your
local
building
official.
To
install
a
large capacity, gravity
fed
external tank,
follow
the
instructions below,
and
refer
to
Figure
21 for
one
possible
installation.
Use of a
qualified installer
is
recommended.
•
Installation
height
of the
bottom
of the
fuel
tank
should
be 16
inches
or
more above
the
floor surface
on
which
the
heater stands. This ensures that
inlet
fuel pressure
will
be
sufficient.
• The top of the
fuel
tank
should
be no
higher than
8>2
feet above
the
floor under
the
heater. Heights
above
8/4
feet will exceed
the 2.5 psi
inlet limit,
and
a
pressure reducer will need
to be
installed
at
or
near
the
unit.
•
The
horizontal length
of
piping should
not
exceed
100
feet
and
should
be
free
of
sharp bends
or
obstructions.
•
Piping should
include
no
inverse
U-type
bends
(to
avoid
air
locks,
which
could
block
the
fuel supply).
•
Only
%
inch
OD
copper
tubing
should
be
used.
The
tubing
should
be
bent carefully
to
avoid crimping.
• A
fuel
filter
is
recommended
for use on the
fuel line
near
the
tank,
and a
shut-off valve should
be
installed
at the
tank.
• A
flare adaptor
can be
used
to
make
a
flared tubing
connection between
the
unit
and the
filter
at the
tank.
• The
fuel tank should
be
located
no
closer than
3
feet
to a
source
of
heat.
•
The
fuel
tank
should have
an
opening
for
filling
on
the top and
vent
with
a
weather-proof
cap on the
side.
On
some tanks
the
vent
and
fill
spout
use the
same opening.
When using
a
gravity
fed
tank
to
supply fuel,
the
inlet
pressure
to the
heater must
not
exceed
2.5
psi.
The
Monitor 2400 comes equipped with
a
3
/a"
pipe
thread
connection.
A
straight,
or 90
degree
pipe-to-
flare
fitting
or a
firomatic
valve
can be
used
for the
fuel line connection.
If a
firomatic valve
is
being
used:
Valve
Position-Open/Close
Turn counterclockwise
to
open, clockwise
to
close.
If
threaded
valve stem
is
sticking
up
about
Y
A
",
valve
is
open.
If
handle screws
off
stem, valve
is
closed.
